ᐅ Concrete wall in shower, seamless walls

Hello. We would like to create seamless shower walls with a concrete look. I know there are various suppliers for this, but their prices are quite high.
Which type of plaster could be used for this, and what kind of sealing would be necessary if we don’t want to go with expensive, well-known brands?

Best regards

Not plaster as a surface at all.

You need a professional solution like Beton Ciré or something similar with the appropriate system sealing. You can do it yourself; how it ultimately looks is another question.

You’re choosing something special. That costs both in materials and workmanship.

Alternatively, consider full-surface shower panels. You can look them up – basically laminate or similar materials for walls in large formats.

I think you are looking for something like _beton Pure_ from Beton Vivet.

Originally, we also wanted to use it as a cost-effective alternative to a coating from Dold.

However, we have since switched back to tiles, even though we’re not really fond of them. But when it comes to price/performance, plain tiles are unfortunately unbeatable. Who would have thought... 😉

Don’t make it so complicated... just go with tiles 🙂 We have washable plaster around the washbasin and bathtub, and even there — no matter what the manufacturers claim — it’s not completely risk-free when it comes to water.

Last week, I visited friends who have matte large-format tiles in a concrete look with concrete-colored grout in their new house. You really have to look closely to even notice where one tile ends and the next begins.

Every tiler I’ve spoken to says that having many grout joints in the shower is problematic. Because sooner or later, each grout joint will erode. That’s why a waterproof membrane has to be installed beneath the tile layer—especially a full-surface one in the shower.

Most grout mortar is cement-based. So is concrete. In a way, you actually have a large joint. Sure, it’s sealed, but every sealant eventually wears out. Not to mention that the quality of the work depends heavily on the installer, both visually and technically.

On the one hand, the high cost is justified because there are many opportunities for things to go wrong. On the other hand, you really need to think it through carefully…

Or back-painted glass or aluminum panels.
Seamless systems like the ones you described or Dold are not less expensive than high-quality tiles.
